KIM and Khloe Kardashian have shown off their trim physiques by donning matching outfits in Sєxy new pH๏τos.

Kim took to Instagram on Monday to share the sultry snaps.

In the pics, the sisters modeled the same ensembles: a long skirt with a high slit, a tiny bra, and bare feet.

They each wore different colors, with Kim sporting a light gray set while Khloe’s was black.

They also styled their hair differently as the Skims mogul opted to keep her long dark locks flowing down, and the Good American founder wore her blonde hair in an updo.

The reality stars stunned in the looks, flaunting their chiseled abs and pin-thin frames throughout the pH๏τo shoot.

In multiple sH๏τs, the KUWTK alums posed while standing on a stairwell; in others, they stood in front of a cream-colored wall.

Kim even had some fun behind the camera as she lay on the ground to capture pH๏τos of her younger sister.

The Skkns founder gushed over the snaps and the pair’s close bond in her caption.

Referring to their nicknames, she wrote “Kiki & Koko” and an emoji of an infinity symbol.

Khloe sweetly replied in the comments: “Forever,” and echoed the infinity symbol emoji.

The youngest Kar-Jenner sibling, Kylie, 25, also remarked: “cutest.”
